Letters Patent No. 98,914, dated January 18, 1870'.

FENDER r012 HEATING-STCBVBS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, NATHANIEL A. BOYNTON, of the city, county, and State of New York, have invented a new and useful Improvement in Stoves; and I do hereby declare the following to be a full, clear,

, and exact description thereof, which will enable those are used on a stove, as to leave an air-space between such fenders and the stove, toward which the rising currents of air will be deflected by the fender, and through which such air can freely pass, in contact with the body of the stove, whereby such air will become heated, and flow upward into thespace above.

It also consists in arranging said fender, so as to form a protecting-shield from the glare of the fire.

The letter A designates the body of a stove, to which my invention is applied.

Its shape is made up of three dilierent incomplete or truncated conical bodies or parts, B O D, the lower one, B, containing the grate and ash-box, and the upper ones, 0 D, constituting the combustion-chamber. Together, they form a symmetrical figure, which is well adapted to the construction of an elhcient stove.

The part 0 is an inverted truncated cone, whose base is united to the base of the upper part I).

At or about the line of their union, I place the annular fender 'E, which is so made and arranged that its inner edge shall be separated from the body of the stove by an annular space, through which air is free to pass, said fender E being supported by three bracket-s F, which extend outward from the stove;

The fender E, thus separated from the stove, will not become as highly heated as it would become, were the fender closely joined to the stove along its inner edge, according to the method commonly practised, and, consequently, owing to the comparatively low temperature at which the fender will be maintained, there will be less liability of injury, byburning, to dresses and clothing, and other articles which come in contact therewith.

The stove here shown has two fenders, or circum ferential flanges, beside the fender E, already de scribed, to wit, one fender, G, around the base of the I stove, and another one, H, around its top. These can likewise be set off or separated froni'the body of the stove by an intervening air-space, and be supported in position by braces or brackets, as above explained.

Another improvement in the fender E consists in its form and arrangement, whereby it is made to serve as a shield, to protect persons who surround it from the glare and injurious effects of direct exposure to rays from that part of the body of the stove which contains the burning fuel, and which part is often red hot.

To accomplish this part of my invent-ion, I make the fender E to extend downward with an increasing diameter, in such a manner as to shield much of the hottest portion of the fire-pot, and protect those per sonsw-ho surround it from the glare and heat.

The fender thus forms a circumferential shield or curtain about the fire-pot, and its extended surface dilfuses, by radiation, a more gentle heat than that coming directly from the fire-pot without this provision, while the' heating-capacity of the stove remains substantially unimpaired, since the air-space I, between the fender and the stove, allows the free passage of currents of air upward, and the air which passes up through such space I is also directed or deflected toward the stove by the shape of the fender, whose sides. contract" toward the top, as is shown in the draw- The fenders can be made partly of open-work, but they should be, for the most part, solid, and they can be of any desired ornamental shape or pattern.

The fender E, which I have here shown, is made with both curved and straight lines, in cross-section, so as to give a pleasing varietyto its shape.

I have found that while, by my invention, the intensity of the heat from the lire-pot is more or less intcrcepterhthe circulation and heating of the air in a room are accelerated, and the heat from the stove becomes more generally and evenlyditt'used through the remoter parts of the room, than is the case without my improvement. Therefore, those persons whose positions are near the stove, will not be made uncomfortable by reason of their proximity, and those whose positions are more remote, will not, on. that account, be deprived of the benefit of the fire.

What I claim as new, and desire to secure by Letters Patent, is-

The extension or fender or shield E downward, so as to form an inter-posing curtain outside of the stove, in combination with the separating air-spacel, substantially as described.
